WHAT IT DOES

What discord_lock_thread does on Discord

AI agents use discord_lock_thread to create or update resources in Discord, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Discord environment.

RISK

Why discord_lock_thread is rated Medium

Locking a thread prevents further messages but does not destroy data or permanently remove the thread. The action is reversible (can unlock later). This is a write operation that modifies metadata/state of an existing resource. The confirmation requirement and low blast radius (limited to a single thread) support low severity.

From the tool's definition Tool name is "discord_lock_thread" and description states it can "Lock/unlock a thread" with a confirmation parameter. Locking/unlocking is a reversible state change that modifies thread properties but does not delete data or cause irreversible harm.

The rule that runs discord_lock_thread safely

discord_lock_thread Rate-limited

discord_lock_thread stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
